geometry, speaker positioning within the room, or even by a less-than-
perfect accuracy in the measurement positions.
This can be solved by using the "Combined L/R Correction" function (figure 5.20).

When this option is selected, ARC 2 will average the correction among the
L/R channels and then apply it symmetrically to the two channels to effec-
tively restore the correct stereo image from any anomalies in the monitoring
(figure 5.21).

5.2.6 Full Range Bass Correction
The ARC System 2 automatically detects the bass roll-off point of each
speaker to ensure that no correction is applied below that point as it may
potentially overload speakers. However, in some rooms with especially odd
low frequency issues, the ARC's measurement system can be misled and set
a Low Frequency roll-off point that is actually higher than what is really
required. This results in no correction applied to low frequencies even if it
was actually needed.
To address this, it is possible to disable the automatic roll-off point detection
feature and allow the ARC's correction to be applied to the entire frequency
spectrum down to 20 Hz, no matter what roll-off point is detected. Please
note that as a safety precaution, the maximum boost applied to the low
frequency range will never be higher than 9 dB to protect your speakers
from excessive boost.
To select this option, simply click the button labeled "Full Range Bass
